This phenomenon is observed in various materials, including metals, minerals, and polymers. Amorphism, on the other hand, refers to the lack of a well-defined crystalline structure in a substance. Amorphous materials do not have a regular arrangement of atoms. 8 In polymorphism, the different ...
There are two classes of solids: crystalline and amorphous. Made up of crystals, crystalline solids tend to fracture along defined surfaces that have a characteristic shape, depending on the arrangement and forces among the atoms or molecules in them. Amorphous solids, however, lack any apparent c...
aWhen cured, epoxy resins produce highly crosslinked, amorphous thermoset polymers. The resulting struc-ture of such polymers possesses many useful engi-neering properties 当治疗时,环氧树脂生产高度被交互相联的,无定形的thermoset聚合物。 发生的结构的这样聚合物拥有许多有用的工程学物产[translate] ...
Thermoplastics are further divided intoamorphous and crystalline polymers. Amorphous polymers are made of randomly tangled molecules, so they have no long-range order. Molecules in crystalline polymers align in folded stacks, which brings long-range order to polymers, like the orderly arrangement of at...
What is Amorphous Silicon? What is Bromine? What is a Dopant? What is a Hybrid Silicon Laser? What are Polymers? Discussion Comments ByDentalFloss— On Oct 12, 2010 Considering that it is the second most common element in the atmosphere, you would thing that people would be more knowledgeab...

This may not happen in most amorphous polymers such as ABS, polycarbonate, and acrylic, since the recommended drying temperatures are normally 20 °F to 30 °F below the softening point. Any major deviation in the drying temperature will rapidly create a sintered mass of material that will not...
